The polarographic behavior of mixtures of anthracene An, fluoranthene Fa and alkali metal cations in N,N-dimethylformamide DMF or acetonitrile ACN indicates that the electrogenerated dianion of the hydrocarbon reacts with the metal cation in the diffusion layer to form ion complexes. This results, in the case of sodium or lithium cations with anthracene in both DMF and ACN, in the appearance of the invented polarographic waves. In the case of other alkali metal cations K, Rb, the intensity of the polarographic wave due to the reduction to the hydrocarbon dianion is simply decreased. The stoichiometries and mechanisms of the interactions are discussed.
